Description

A kind of polygonal adjustable spanner

Technical field

The invention belongs to machine tool field, be specifically related to a kind of novel polygonal adjustable spanner.

Background technology

Traditional spanner is generally divided into fork spanner and adjustable wrench.Fork spanner one or both ends are shaped with the clamp holder portion of fixed dimension, in order to twist nut or the bolt of fixed dimension.The flexibility of fork spanner application is poor, and the scope of application is more single.Adjustable wrench one end A/F can regulate within the scope of certain size, can twist bolt or the nut of different size, but adjustable wrench uses and waste time and energy, not too convenient.Be badly in need of a kind of novel adjustable spanner for this reason and solve the problem that above all kinds of spanner runs at work.

Summary of the invention

The object of the invention is: overcome the deficiency that in background technology, traditional fork spanner and adjustable wrench exist, provide a kind of simple in structure, easy to operate, security and reliability is high, the spanner of applied range.

To the effect that a kind of novel widely applicable adjustable spanner of this patent, wrench body coordinates assembling by main handle (seeing Fig. 2, Fig. 3), auxiliary-handle (seeing Fig. 4), main handle forms by upper and lower symmetrical 2, by bearing pin, is connected or is welded and fixed, and whole interior is dead slot.Auxiliary-handle head inserts in main handle head dead slot.On auxiliary-handle, around Clamping Center, have Long Circle through hole, the number of Long Circle through hole is the limit number of institute's nutting or bolt, and the angle of every two adjacent Long Circle through holes is the angle of institute's nutting or bolt adjacent two edges.On main handle head, along radial direction, have U-shaped through hole, and form certain angle with the Long Circle through hole of auxiliary-handle head, the number of U-shaped through hole is the limit number of institute's nutting or bolt.In the U-shaped through hole of main handle, have the slip clamp jaw (seeing Fig. 5) matching, the disjunct two ends of slip clamp jaw have aperture, and bearing pin links together their threes by slip clamp jaw aperture, the U-shaped through hole of main handle and auxiliary-handle Long Circle through hole.

The operation principle of this polygonal adjustable spanner is: when main handle 1 and auxiliary-handle 2 being applied to the outer face of inside external force clamping nut or bolt, slip clamp jaw 3 can slide along the U-shaped through hole ecto-entad of main handle 1 head, connect bearing pin 4 when the U-shaped through hole ecto-entad along main handle 1 head slides, also along auxiliary-handle 2 head length round tube holes, slide, with the angle realizing between two handles, change, when the compression of the outer face of the clamping end face of slip clamp jaw 3 and the nut that will twist or bolt, realized clamping function, then rotation realizes and twists function.As shown in Figure 1, the minimum state of clamping as shown in Figure 6 for the maximum rating of clamping.

A polygonal adjustable spanner, is characterized in that, comprises main handle 1, auxiliary-handle 2, slip clamp jaw 3, connects bearing pin 4 and main handle bearing pin 5;

Main handle 1 is comprised of two main handle lamellar bodies 6, main handle lamellar body 6 is divided into head and handle body, and head has a manhole and a plurality of U-shaped through hole, and this U-shaped through hole is circumferentially uniformly distributed along manhole, U-shaped through hole center line is by the center of circle of manhole, and is communicated with manhole;

Auxiliary-handle 2 heads have manhole, radius is identical with main handle 1 head manhole radius, at this through hole, be uniformly distributed a plurality of Long Circle through holes around, Long Circle through hole and manhole do not connect, and it is regular polygon that Long Circle through hole center line or center line extended line intersect the polygon forming;

Slip clamp jaw 3 is U-shaped, and two U-shaped arm end relative positions have through hole;

Two main handle lamellar bodies 6 of main handle 1 are connected by main handle bearing pin 5, auxiliary-handle 2 heads insert between two main handle lamellar bodies 6 of main handle 1 head, three manhole center of circle alignment, 3 two support arms of slip clamp jaw stretch into U-shaped through hole, and connection bearing pin 4 couples together three through the through hole of U-shaped through hole, auxiliary-handle 2 head length manholes and the slip clamp jaw 3 of main handle 1.

The U-shaped through hole number of described main handle head is 3～12.

Described auxiliary-handle head length manhole number is 3～12, and identical with the U-shaped number of openings of main handle head.

Described slip clamp jaw 3 numbers are 3～12, and identical with the U-shaped number of openings of main handle head.

Described connection bearing pin number is 3～12, and identical with the U-shaped number of openings of main handle head.

Described main handle bearing pin number is 2～10

Adjustable spanner that this patent provides is simple in structure, easy to operate, security and reliability is high, applied range, can twist nut or the bolt of the different size specification of 3～12 jiaos, reduce the use of fork spanner and opening movable spanner, can increase substantially operating efficiency.
